MACHINE FOR CASTING ANODE-PLATES.

Specification of Letters Patent.

vmetals and objects of a similar character made of soft metal, such as lead and copper. The object of my invention is a machine that will work automatically and rapidly and with molds that are less subject to breakage from expansion and contraction.

Figure 1 is a plan of in improved machine. ,Fig. 2 is a vertica transverse section of the same. Fig. 3 is a face view of one of the molds on a larger scale. Fig. 4:

I is a longitudinal section of the mold on line -1-4, Fig. 3, partly in elevation. Fig. 5 is a transverse section of the same, on line 55, Fig. 3, and Fig. 6 is a view of the plate or anode produced by the machine.

Upon a suitable foundation, such as the base plate A, is secured a vertical stud or axle, B, upon which is journaled a lar e bevel wheel, C, gearing into a pinion, which is fast upon a driven shaft, D journaled .upon sald base and below the bevel wheel C. Radial arms, C are secured upon the bevel wheel 0 which, at their outer extremities, carry brackets. These brackets may be of any suitable description, but in the construction illustrated, they consist each of a. vertical post, E, a horizontal outward projecting member, E an inner brace, E secured to the arm C and an outer bracket, E supporting the horizontal limb. Each arm carries a pair of these brackets, diverging as shown in Fig. 1. An annular plate, F, is secured upon these brackets, above the post E; thus forming with the brackets, arms C andwheel. C a rigid horizbntal table having a rotary motion in the'direction shown by the arrow in Fig. 1. As this table is required to be very rigid and steady, the posts E may be prolonged downward and bear upon a track, A, by means of a sliding foot, e or friction roller. The track A may be integral with or be secured to the base A. The floor, a,

under the base is inclined preferably toward the center, and a drain, A, is proand cool them.

vided to carry off the water used in spraying and cooling. The brackets E E at their outer extremities carry bearings, E, adapted to receive the trunnions of the molds. A mold is placed between each two arms G and the brackets E E adjacent to each mold are disposed parallel and close to it, one on each side. I

The molds, G, are each composed of three parts, as shown in Figs. 3, 4 and 5 and are adapted to what is known as open casting, z. e., held flat or in a horizontal osition, open at the top and adapted to orm the anode H. The main or body part is in two sections, 2 and 3, joined longitudinally and medially with a tongue-and-groove jolnt, 5, and held together by bolts, G which may pass through the late and have sprin s, G inserted between t e sides and the hea s and nuts-the springs com ensating for expansion and contraction. rim, 9, runs around one end and both sides, determining the thickness of the plate to be cast. 'Trunnions, 9 may be integral with and project from the sides, their axis placed between the center of gravity of the finished late and its head, so that the plain end is eavier than the head end. The trunnions g are journaled in the bearings E on the brackets and this part of the mold is thus pivotally mounted. The head section, 4, is separate; it is joined to the main part with a beveled joint,

6, sloping from the face to the back and,

position and joined to the heads by a rail, 1,

extending part around the circle, secured to the base and upon which the back of the molds bear. The ends of this rail are curved, one, i, Fig. 1, which the molds meet first in the course of the rotation, inward, so as to engage the back of the hanging molds and raise them in osition ready for filling; the other end, i igs. .1 and 2, curved downward to allow the molds to tilt.

J indicates the spout or filler; it discharges upon the mold that has been first raised into position.

K is a perforated water pipe, nearly coextensive with the rail'I and ads. ted to spray the back of the filled molds wit water til ale-.

To prevent the tilting section of the mold from failing to upset after leaving the rail I, a pulley L, acting like an inclined plane which the open molds G are hung on truni tion ready for filling again.

nions, held fiat and making joint with the fixed heads for filling by sliding upon a circularrail. This rail I which by lts curved end a first picks up the depending end of the mold, holds the latter flat and steady while passing under the filler 'J and until it reaches the tilting device 2' and L. The

filled mold, always in motion, moves on and passes over the spray pipe, the metal in it cooling and setting until t arrives at the point where the rail I dips. The mold is now ,free to tilt, upset and dump the casting, the pulley L assisting in the latter operation and thus the casting is removed. In tilting, the main part of the casting H lifts the head from the fixed head part of the mold. After upsettin the mold remains suspended until the en 7; of the rail picks it up again and it is tilted up'back into posi- The mold being in three pieces and two of them yieldin 'ly connected, while the head parts from t em at a plain joint, reduces the tendency to crack from unequal expansion and contraction to a minimum;

It will be selfevident that the shape of the casting produced by this machine is not confined to the shape of the anode H shown and that the shape of the mold will, of

course, vary with that of the desired casting.

I claim as my invention:- 1. In a casting machine, the combination with a base of a vertical axle, a bevel wheel journaled upon said axle, a bevel pinion gearing into said bevel wheel, an axle journaled upon said base and carrying said pinion, radial arms secured upon said wheel, av pair of brackets secured upon the free end of .each of said arms, an annular plate secured upon said brackets, a bearing secured upon each bracket, a mold head securedupon said plate between each pair of arms, an open swivel sectionmold with trunnions journaled in said bearings and making joint with the head section, a rail with curved ends extending partly around the circle and journaled'thereon, a bevel pinion geared in saidwheel, a shaft carrying said pinion,

radial arms secured to said wheel, a pair of brackets at the end of each arm, an annular plate secured upon said brackets, a bearing at the projecting end of each bracket, a moldv head secured upon said plate betwe'en each pair of arms, an open'swivel mold section with trunnions j ournaled in the bearings of the brackets and making joint with the head and a horizontal circular rail with curved ends extending partly around the circle under and supporting some of the pivoted sec tions of the molds, substantially as set forth.

3. In a casting machine, the combination with avbase of a horizontal rotary table mounted thereon, means of giving a rotary motion to said table, a series of pairs of horizontal bearings on the periphery of said table, a mold-section with trunnions journaled in each pair of bearings, a head section of the mold secured to the table adjacentto each pivoted section and making joint therewith and a horizontal circular rail with curved ends extending under and supporting some of the journaled sections,

substantially as set forth.

4. In a casting machine mold, the combination of a plate divided longitudinally and joined with a ton e-and groovejoint, bolts placed transversey to said joint, a coiled spring upon the ends of saidbolts extending between the sides of the plate and the head and-nut respectively, a rim on one end and two sides of said plate, a beveled edge on the other end of said plates, a trunnion on each side of said plate adapting it to be pivotally hung and upset, a head sect-ion conforming to said swivel section adapted to be fixed into position and provided with a beveled edge fitting the beveled edge of the-swivel section 'and allowing the latter to swing upward, substantially as set forth.
